Table 5 The best-case scenarios of physical, mental and autonomy decline in frail, pre-frail and robust persons according to the Puts, Frieds and Steverink–Slaets models in the Crystal population

From: Do commonly used frailty models predict mortality, loss of autonomy and mental decline in older adults in northwestern Russia? A prospective cohort study

  Mental decline OR (95 % CI) Autonomy decline OR (95 % CI) Physical decline OR (95 % CI)
Puts model
 Frail 0.89 (0.45–1.75); p = 0.74 2.27 (0.51–10.12); p = 0.28 0.81 (0.45–1.48); p = 0.50
 Pre - frail 1.09 (0.54–2.17); p = 0.81 2.62 (0.57–11.94); p = 0.21 0.93 (0.50–1.72); p = 0.81
The Steverink – Slaets model
 Frail 0.62 (0.37–1.06); p = 0.82 1.98 (0.79–4.96); p = 0.15 0.59 (0.37–0.96); p = 0.03
  (0.60 (0.36–0.99); p = 0.44)*
 Pre - frail 0.96 (0.56–1.63); p = 0.87 2.41 (0.94–6.17); p = 0.67 1.04 (0.643–1.68); p = 0.89
Fried model
